HARRY E. WEISGERBER, OF ATLANTIC CITY, NEW JERSEY.

ROLLING-CHAIR.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed April 18, 1902. Serial No. 103,579.

To aZZ whom, it may concern:

Be it known that I, HARRY E. WEIseERBER, a citizen of the United States, residing in Atlantic City, county of Atlantic, State of New Jersey, have invented a new and useful Improvement in Rolling-Chairs, of which the following is a specification.

My invention consists of a novel construction of a rolling-chair, as will be hereinafter fully described and claimed.

Figure 1 represents a side elevation of a rolling-chair constructed in accordance with my invention, partially in Vertical section and with parts removed for convenience of illustration. Fig. 2 represents a vertical transverse section taken partially on line w 00 of Fig. 1. Fig. 3 is a perspective view of the yielding connection between the chairbody and the running-gear. Fig. 4 represents a sectional detail view.

Referring to the drawings, A designates a suitable frame having the main carryingwheel B, it being understood that the forward end of said frame is provided with suitable wheels in the usual manner, but which are not herein shown. The handle G is suitably attached to the frame and serves as a means by which the chair may be pushed.

The chair-body is provided with the front uprights D and rear uprights E, the latter extending higher than the former to provide a suitable frame for the back F. The armrests G extend between said uprights D and E. The rear uprights E have an extension H, depending below the seat J, from the lower end of which extend forwardly the horizontal frame-pieces K on the outside of the wheels B, which are suitably connected with the depending portion L on the front uprights D, the latter being connected with a cross-bar M, which is secured to the side pieces of the frame A, and is provided With a transverse seat or socket P in its upper side in which said cross-bar rests, the latter being held in place within the sockets in said blocks N by means of bails or straps Q, the ends of which are secured by means of the plates R and nuts S.

The rear portion of the chair-body is conveniently supported by means of a spring T, (shown in Fig. 1,) it being understood, however, that elliptical or other forms of springs may be substituted. are not sufliciently tight to prevent the crossbar M from turning, so as to form a pivot or hinge, and the springs or cushionsT yielding The straps or bails Q,

support the chair-body when it rocks upon the pivotal connection between the cross-bar M and the frame of the chair.

I also provide a removable top and side and rear sashes for the chair. The top consists of the roof U, provided at the front and rear of the sides thereof with the posts V and WV, the lower ends of said posts being reduced, as at X, to form pins to enter the sockets or recesses Y in the upper ends of the uprights D and E and shoulders to support the top. From. this it will be seen that the top can be removed by lifting and the posts V and W folded, so that it can be stored within a small compass. The top is pivotally connected with the posts V and W in any suitable manner, so as to be foldable thereagainst. One convenient form of such pivotal connection is herein shown at V.

I also provide side and back sashes for the chair, to be used when the top is in place, and to hold the side sashes in position the top piece is provided with a guide-bar Z, projectinglaterally and having a suitable groove Z in its lower side, which is situated just over the groove A in the arm G, the side sashes B fitting within and being held in place within these grooves. It is understood, of course, that the sashes B are shaped to conform to the front post V and the rear post W and uprights E. It Will also be seen that the sashes act to prevent racking movement of the uprights W and V at their pin-and-socket connections. The rear or back sash G rests at its lower edge within a groove D in the crossbar E at the top of the back F, while its upper end fits the rear end of the top piece U and is held in place by means of slide-bolts F, carried by the sash O, situated at the sides thereof and adapted to enter suitable openings in the bar Z.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a rolling-chair, a chair-body havinga bodily, vertically removable top with posts forming continuations of those of the body, and removable sashes adapted to engage said chair body and top when the latter is mounted upon the former.

2. In a rolling-chair, a chair-body having upwardly-facing grooves, a bodily, vertically removable top having downwardly facing grooves, and removable sashes adapted to enter said grooves when the top is mounted upon the chair-body.

IIO

8. In a rolling-chair, a chair-body having grooves in the arm-rests thereof, a removable top having folding supporting-posts and a grooved side bar, and sashes adapted to enter said grooves when the top is mounted upon the chair-body.

4:. In a rolling-chair, a chair-body havinga grooved cross-piece at the upper end of the back, a bodily, vertically removable top, a sash adapted to entersaid grooved cross-piece, and means for securing the upper end of said sash to said top.

5. In a rolling-chair, a chair-body having a grooved cross-piece at the upper end of the back, a bodily, vertically removable top, a sash adapted to enter said grooved cross-piece and provided with means at its upper end to engage said top.

6. In a rolling-chair, a body, a top removable from said body, a plurality of posts each having pivotal connection with said top and pin-and-socket connection with said body, and means removable from said chair for preventing racking motion of said posts.

7. In a rolling-chair, a body, a top removable from said body, a plurality of posts between said top and said body and havingpivotal connection With one of said parts and pinand-socket connection with the other of said parts, and separate removable means between said posts for preventing racking motion of said posts.

8. In a rolling-chair, a body, a top removable from said body, and a plurality of posts having pivotal connection with said top and pin-and-socket connection with said body, and means engaging with said body and said top intermediate said posts for preventing racking motion thereof.

9. In a rolling-chair, a chair-body having front and rear uprights a top having depend ing posts forming vertical continuations of said uprights, laterally-projecting guide-bars on said top, removable sashes engaging said guide-bars and body, and a removable rear sash provided with means engaging the said guide-bars for locking said sash in position.
